TEAS 7 Math Practice Test

Correct Answer: D

Rationale: To calculate the sale price Gordon paid, we first find the discount amount by multiplying the original price by the discount percentage: $472 * 0.30 = $141.60. The sale price is the original price minus the discount amount: $472 - $141.60 = $330.40. Therefore, the correct answer is D. Choice A is incorrect because it only represents the discount amount, not the final sale price. Choice B is incorrect as it does not account for the discount. Choice C is incorrect as it is higher than the correct sale price.

Correct Answer: D

Rationale: The correct answer is D: 0.16%. To find the percentage equivalent of a decimal, we multiply the decimal by 100. So, 0.0016 x 100 = 0.16%. Choice A (16%) is incorrect because it represents the decimal as a whole number, not a percentage. Choice B (160%) is incorrect as it incorrectly multiplies the decimal by 1000 instead of 100. Choice C (1.60%) is incorrect as it incorrectly places the decimal point in the wrong position, resulting in an incorrect percentage value.

Correct Answer: C

Correct Answer: B

Rationale: To find the approximate number of people who voted for the proposition, we multiply the town's population by the percentage that voted: 51,623 * 9.5% = 51,623 * 0.095 = 4,904. Therefore, approximately 5,000 people voted for the proposition. Choice A (3,000) is too low because 9.5% of the population would result in more voters. Choice C (7,000) is too high because it exceeds the calculation based on the given percentage. Choice D (10,000) is also too high as it overestimates the number of voters based on the percentage provided.

Correct Answer: B

Rationale: To determine the order of groups from smallest to largest, we need to compare the fractions given for each group. Given that 4/15 < 2/5 < 1/3: 1. Group Alpha (4/15) < Group Beta (2/5) < Group Gamma (1/3) Thus, the correct order is Group Alpha, Group Gamma, Group Beta (B). The rationale is based on comparing the fractions numerically to determine the relative sizes of the groups. The other choices are incorrect because they do not follow the order of fractions provided in the question, leading to incorrect group size comparisons.
